Selena Gomez is apparently selective about who she will discuss Justin Bieber with.

While doing a satellite media tour Monday ― her 21st birthday ― to promote her upcoming Stars Dance Tour, Gomez was probed about her off-again/on-again boyfriend Justin Bieber's recent bad boy behavior, and apparently it wasn't a topic she felt like discussing as the interview abruptly came to a shrieking halt.

WGN-TV entertainment critic Dean Richards was among the outlets talking to Gomez during her media blitz. “You're, you know, probably as close a friend to Justin Bieber as they come," he said. "Is there something about him that we don't get or we don't understand? I mean, there is one story after another of, you know, pretty outrageous behavior that we're reading about.”

At first the "Come & Get It" singer looked down uncomfortably ― almost as if she were wishing away the awkward situation ― then she smiled to someone off camera. Despite her obvious hesitation, Richards pressed on, following with, “What don't we get about him or what is it that he's not getting out there?”

But before giving any insight into life with Bieber ― which Gomez opened up about the night before during her interview with Ryan Seacrest (she claims she's single despite their recent Instagrams) ― the feed was suddenly terminated and the "Spring Breakers" star's pretty pout disappeared from the screen. Richards then sort of chuckled to himself as he realized that had been disconnected.

A rep for Gomez has not yet responded to omg!'s request for comment so it's unclear if she was disconnected on purpose or if it was some type of glitch, which is known to happen during satellite tours. The timing seems to indicate it was no accident.

Meanwhile, an old interview with Bieber has surfaced that should give fans of the couple some hope of another reconciliation. During a 2009 sit-down with KIIS-FM ― before he started dating Gomez (and back when he wore shirts!) ― the 19-year-old Canadian singer was asked to name his celebrity crush.

"Selena Gomez," he quickly replied, before adding, "No one heard that. Keep that on the DL."

Their relationship was a long time in the making apparently and we suspect there will be many more chapters ... whether Gomez wants to discuss them or not.
